Predictors of objective sleep tendency in the general population
Abstract
STUDY OBJECTIVES: Daytime sleepiness is a pervasive problem that is associated with a significant public-health burden. Although self-reported measures of daytime sleepiness may be useful in identifying at-risk individuals, there is significant controversy because there are no population-based data relating subjective and objective measures of daytime sleep tendency. The aims of this study were to examine the associations between the Multiple Sleep Latency Test (MSLT), an objective measure of daytime sleep tendency, and self-reported information on the Epworth Sleepiness Scale (ESS) and nighttime sleep duration in the general population. DESIGN: Cross-sectional study. SETTING AND PARTICIPANTS: Population-based sample of 261 women and 371 men, mean age of 50.8 years, enrolled in the Wisconsin Sleep Cohort Study. MEASUREMENTS: MSLT, ESS, and self-reported sleep duration prior to the MSLT. RESULTS: Using survival analysis to model the time to sleep onset during the MSLT, we found that individuals with an intermediate (6-11) and high (> or = 12) ESS score had a 30% and 69% increase in risk for sleep onset during the MSLT, respectively, compared to individuals with a low ESS score (< or = 5). A dose-response relationship between self-reported duration of nighttime sleep and objective sleep tendency was also observed. Compared to individuals reporting more than 7.50 hours of sleep (highest tertile), individuals reporting 6.75 to 7.50 hours and less than 6.75 hours (lowest tertile) had a 27% and 73% increase in risk for sleep onset during the MSLT, respectively. CONCLUSIONS: Subjective reports of daytime sleep tendency on the ESS and the duration of nighttime sleep are associated with the results of the MSLT in the general population.

A more recent study showed that adults reporting sleep durations of 6.75 to 7.5 hours, and less than 6.75 hours, had a 27% and 73% increase, respectively, in the risk of sleep onset during the MSLT, compared to adults reporting >7.5 hours of sleep.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
